2.Association between insulin resistance and coronary artery disease
Chinese Journal of General Practitioners 2005;0(07):-
Objective To study the effect of insulin resistance on the development of coronary artery disease ( CAD). Methods In total, 204 nondiabetic inpatients diagnosed by elective coronary angiography were selected in the study and divided into CAD and control groups. Relationship between insulin resistance assessed by homeostasis model ( HOMA-IR) and fasting serum level of insulin and occurrence of CAD and the extent of stenosis of coronary arteries was analyzed. Results IR and serum level of insulin were significantly higher in CAD group than those in control group ( P

Objective To analyze strains of Proteus mirabilis (P .mirabilis )and Proteus vulgaris (P .vulgaris ) isolated in a hospital,detect resistance to commonly used antimicrobial agents,and provide reference for rational ap-plication of antimicrobial agents in clinic.Methods 172 P .mirabilis isolates and 68 P .vulgaris isolates isolated between January 1 ,2011 and June 30,2013 were analyzed,antimicrobial resistance susceptibility testing were per-formed by disk diffusion method,data were analyzed with WHONET 5.4 software.Results P .mirabilis strains were mainly isolated from wound secretion(26.74%),sputum(22.68%)and urine(18.61 %),P .vulgaris were mainly from wound secretion(48.53%),urine(17.65%)and sputum(11 .77%).The resistance rates of P .mirabilis to ampicillin and trimethoprim/sulfamethoxazole were both>45.00%;the resistance rates of P .vulgaris to cefazo-lin and trimethoprim/sulfamethoxazole was 86.76% and 41 .18% respectively;the resistance rates of P .mirabilis and P .vulgaris to piperacillin/tazobactam,cefotaxime,ceftazidime,cefepime,carbapenems (ertapenem and mero-penem)and amikacin were all <20.00%.Conclusion The resistance rates of P .mirabilis and P .vulgaris to pip-eracillin/tazobactam,cefotaxime,ceftazidime,cefepime,ertapenem,meropenem and amikacin are all high,and can be used as the empirical medication for the treatment of related infection.

Objective:To display human CD137 extra-cellular domain on phage using phage display technique and detect its antigenicity and bioactivity.Methods:CD137 extra-cellular gene was amplified from CIS plasmid using PCR and then clone it into pComb3HSS.The recombinant pComb3H-CD137 was transfected into competent bacteria XL1-Blue, then the transfected bacteria was co-infected with help phage VCSM13 and CD137 extra-cellular domain was displayed on the phage surface. The antigenicity and bioactivity of CD137 displayed on phage was detected by ELISA and inhibition assay of lymphocyte proliferation(MTT).Results:CD137 PCR products was 525 bp, the recombined plasmid was named pComb3H-CD137, CD137 was displayed on phage. ELISA detection showed that phage displayed CD137 possesses antigenicity of human CD137. MTT inhibition assay showed that lymphocytes proliferation stimulated by PHA and CD137 could be inhibited by phage displayed CD137, indicating that it has bioactivity of nature CD137.Conclusion:The studies demonstrate that phage display system can display human CD137 extra-cellular domain homodimer with antigenicity and bioactivity.

ObjectiveTo explore the clinical characteristics and the relationship between rational therapy and prognosis in primary central nervous system lymphoma (PCNSL).MethodsClinical data of 23 patients pathologically confirmed as PCNSL and treated in our hospital from January 2005 to December 2007 were collected and analyzed retrospectively.SPSS 13.0 statistical analysis software was used to analyze the correlation between therapy,clinical characteristics and prognosis.Among the 23 patient,10 were male and 13 were female,with a median age of 50 (2-75) years old.Eighteen patients were undertaken lumbar puncture,and tumor cells in cerebral spinal fluid (CSF) was found in 4 patients.Tumorectomy was performed in 8 patient,while 15 patients biopsy.Among them,4 accepted whole brain irradiation,6 accepted associated chemotherapy based on a high-dose of methotrexate (MTX)and 13 accepted radiotherapy combined with chemotherapy.Results Kaplan-Meier analysis showed that in this serial patients,the median survival time was 45.0 months and the 3-year survival rate was 56.5%.Log-Rank test revealed that the whole survival time and the non-progression survival time of radiotherapy combined with chemotherapy (43.8 and 30.0 months,respectively) and high-dose MTX chemotherapy ( 39.7 and 29.7 months,respectively )were much longer than those of radiotherapy alone (25.7 and 19.8 months,respectively,all P < 0.05 ).Log-Rank test showed no significant difference between high-dose MTX chemotherapy alone and radiotherapy combined with chemotherapy (P >0.05 ),but the whole survival time was much shorter in high-dose MTX chemotherapy ( P < 0.05 ).ConclusionsThe detection of tumor cells in CSF can confirm the diagnosis,but pathological biopsy is the gold standard.The efficacy of associated chemotherapy based on a high-dose of MTX combined with radiotherapy is much better than radiotherapy or chemotherapy alone.

In order to establish a simple and useful way for preimplantation genetic diagnosis (PGD) of chromosomal diseases in general IVF laboratory, the methods that are most commonly used in the embryo biopsy, fixation of blastomere and fluorescence in situ hybridization were compared. The three aspects of PGD were analyzed respectively. There was no significant difference in further development capacity of embryos between mechanical (79.7%) and chemical biopsy group (78.6%) (P>0.05). In this study, more cells were successfully fixed with the Tween/HCL method (93.8%) than with the methanol/acetic acid method (80.5%, P<0.05). There was no significant difference in cytoplasm remains between methanol/acetic acid method and Tween/HCL method (P>0.05). The hybridization efficiency of fluorescence in situ hybridization was 89.5% in successive denaturation method and 90.9% in codenaturation method with the difference being not significant (P>0.05). In conclusion, the mechanical or chemical method, Tween/HCL fixation method and codenaturation fluorescence in situ hybridization method can constitute a simple and useful way for PGD of chromosomal diseases.

18F-fluorodeoxyglucose positron emission tomography-computed tomography (18F-FDG PET-CT) is the integration of functional imaging and anatomic information,which is found to be particularly valuable in TNM staging,tumor volume delineating,post-treatment assessment,identification of recurrent and residual nasopharyngeal carcinoma (NPC).The combination of 18F-FDG PET-CT with other image technologies,different tracer agents,and specific molecular biomarkers can improve the application value of 18F-FDG PET-CT in NPC.
